Ectoplasm is a Hardmode post-Plantera crafting material dropped from Dungeon Spirits in the Dungeon. Dungeon Spirits drop 1–2 Ectoplasm upon death. It is used by Old-gen console version Old-gen console and 3DS3DS version players to directly craft the Spectre armor and tools. On the Desktop version Desktop version, Console version Console version, and Mobile version Mobile version, players use Ectoplasm to craft Spectre Bars, which in turn are used to craft Spectre armor and tools.

On the Old-gen console version Old-gen console version and 3DS3DS version version, the player needs to acquire 136 Ectoplasm and 126 Chlorophyte Bars to craft all Spectre equipment including the tools, wings, armor and both forms of headgear. For just all the components of the Spectre armor set (including both forms of headgear), the player will need 66 Ectoplasm.

  • Due to the difficulty of the Dungeon in Hardmode, Hallowed armor or higher is recommended when farming Ectoplasm. It may take multiple trips to acquire enough for all items.
  • Ectoplasm is a very good source of coins, as each piece of ectoplasm is worth 50.
    • Old-gen console version3DS version If the player has enough spare Souls of Flight, it may be desirable to craft Ghost Wings instead of simply selling the Ectoplasm, as each set of wings is worth 8, while the components are worth less. With a beneficial modifier, the wings might even sell for more. On the Desktop version Desktop version and Mobile version Mobile version selling the ingredients instead will yield 1040.


  • Ectoplasm is a fictitious ethereal substance appearing in fictional works that ghosts and other entities leave in the mortal realm, usually when destroyed.
